'lliisfinventionfrelatestogmotoi: agricultural machines of; thetype having a; rear tractor and; corner turning wheel. and ajlateially-ex# tendingjimplement.as aV mower bar such as set forth -in patent to Brown, No;1l,247,073,` dated November 20, .L9-l7;and;hasfor its object a; nelativearrangementf of the frontvvheel',V

tractor and corner-turning wheel,A and.v mower bar, by which. the machine canbeturned at;

a cornerbef'ore the knife,hfascutr a swath entirely through the standin'gg'rainv orgrass along one side of the uncut crop, and the front end of the machine moved forwardly around the corner and the knife positioned contiguous to the end of the uncut swath at the corner so that when the machine is startedy forwardly, theY knife immediately enters the vuncut portion of such swath;v thus avoiding loss of time maneuvering at cornersl and in' moving the machine and knife up to the uncut crop, and raising the bar.

En describing my invention, reference is had to the accompanying drawing which is f a plan view of a motor mower embodying my tuinable about an upright axis from straight` position whereby both front and rear wheels invention, the standing crop being shown Aand the position of the machine prior to turning the corner being shown in dottedv travel in an arc having substantially the same ferent directions or sectors whereby the front advances forwardly around the corner of the 'standing crop, and a mower'bar or knife or c wheel.

, 12 is the mower knife extending laterally from the 'frame bar l from a point located in the rear of the axis O B so that when the machine is turned from the position indicated in dotted lines to that shown infulllines the knife 12 comes in position to enter the uncut crop immediately when the machine is started forwardly so that no time is lost moving the knifeover stubble or cut crop up to the uncut crop, and raising the bar.

n The movable parts of the lcutting mecha nism are actuated in any well known manner from the motor.

In operation, the driver who is seated `on a seat at the rear of the frame bar 2 drives y the machine to .cut a swath along one side of the standing grass or grain until the standing grass yor grain is nearly cut through Y andthe front Wheel is nearly at the corner. He then operates the controlling mechanism forrt'urning'the wheelvtov angular position.` TWhen the wheel is stopped in' angular position, therear of the machine swings in the. arc Gr and the Wheel 5 advances around the y corner in'the'arc E D without operating the tillerY wheel l() and without raising the bar.

y When t-he frame l is straight withthe edge of the uncut crop after the wheel 5 has turned the corner, theY knife is ready to enter the standing grass or grainV without manipulating the bar, without further maneuvering,

, and withoutmoving the machine up tothe standing grass or grain. In horse drawn, and tractor drawn and other motor mowing ma-V chines, when the machine isshifted in maneuvering or turning acorner, the outer shoe of the mower knife sweeps into the uncut crop, unless the bar is raised, and the machine must beV moved a considerable distance to bring the knife up tothe standing crop. Y

By my mower much time and labor 1s saved vas maneuvering at the corner is eliminated and also damage to the standingl and cutV crop avoided.

The operator 'again' operates the control Vfor the Vwheel 6 so that it rst turns back to In a motor mowing machine, Va lengthwise main frame having a supporting wheel at its frontend and a corner turning and tractor wheel at its rear end arranged to normally move Vin a straight line one behind the other,

Va mower knife extending laterally'from the main frame in therear of the axis of rotation of the front wheel and near the front end of the frame, the tractor and corner turning wheel being movable into an angular radial position whereby it travels in an arc having approximately the same center as the arc of travel of the front wheel when the machine is turning a corner, the rear corner turning and tractor Vwheel when in angular position being so arranged relatively to the front wheel that a continuation of the axis of ro tation of the rear wheel intersects a Continuation ofthe axis of rotation of the front wheel when in straight position at a point on the inner side of the frame in front of the mower knife whereby bot-h front and rear wheels travel when turning a corner in arcs having approximately the same center located on the inner side of the front wheel in front of the mower knife.

In testimony whereof, I haveV hereunto signed my name, at Syracuse, in the county of Onondaga and State of New York, this 1st day of February, 1923.
